CUTHBERT BURNETT, OF DURHAM, ENGLAND Specification of Letters Patent.

. Patented April 23, 1907.

Application filed February 12,1906. Serial No. 800,662.

To all whom it may concern:

Be it known that I, OUTHBERT BURNETT,

a subject of the Kin of Great Britain and Ireland, residing at elmont House, Dur-' ham, England, have invented a new and useful Resilient Tire for Motor-Car and Similar Wheels, of which the following is a specification.

The object of this invention is to produce a tire offeringfa suitable amount of resiliency, greater security against puncturing, and simplicitypf construction and mode of application.

The invention consists essentially in a rubber tire with-a flat or nearly flat. or other known suitable tread face, a chambered out inner art, and a flange or extension on each side, t ese'iflanges bein applied against the rounded edges of a stee or other metal hoop or flange on the telly or wheel rim. a lashing rin bemg rovided on each side, and bolts nuts or forcing the tire flanges against the edges of the hoop or flange on the felly or wheel rim and so make air tight joints. The interior or chambered part of this tire thus forms a tube which can be supplied with compressed air in the usual way through a valve and a tube passed through the felly 'or wheel rim.

I shall now describe several typical forms of this tire. t

tire in the act of being applied to a wheel,

Fig. 2 a cross section when xed and Fig. 3 a sectional elevation of part of'same. Fig. 4 is a cross section similar to Fig. l but formed with cells on the inside and Fig. 5 a sectional side elevation. Fig. 6 is a cross section of one form of tire applied to a metallic wheel. Fi s. 7, 8, 9, and 10 show different forms of cel s.

In Figs. 1, 2 and 3, the rubber tire a is made with an inner part or space e and flange extensionsdf f which are applied against the rounded e ges of a steel or other metal hoop g on the folly b of the wheel. 0 c are lashing rings which by means of the bolts (Z and nuts or equivalent meansforce thetire flange extensions f against the rounded edges of the hoop g so making air-tight joints. The

space e or tube thus formed can be supplied with compressed air in the usual way through a valve and a tube It.

Fi 4 shows a tire with a double row of cells and Fig. 5 a sectional elevation of same to a smaller scale.

Fig. 6 shows the tire in one form as a plied to a metallic wheel which is formed with flanges g.

In some of the forms of tire an inner usual inflatable tube may be applied,

The cells formed on the under side of the tires may, as indicated by be of the form shown in Fig. 7 viz: in one row, or in one row but slanting as in Fig. 8, or in two parallel but staggered rows as in Fig. 9 or in two oppositely slanting rows as in Fig. 10. These cells form eflicient air cushions even without inflation by compressed air, or in case of a puncture all the cells except the unotured one will form air cushions. In t e case of the arrangement, Figs. 9 and 10, if one cell should be punctured, the cells in the adjoining row Wlll to a great extent support the punctured cell, as the air in the cells will form cushions under compression that is to say when coming on the tread.

When a cellular tire is being inflated the divisions between the cells will, one after the other as the inflating ressure is increased, be lifted from the meta hoop g and allow the com ressed air to fill them all.

at I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of a Wheel, a metallic rim thereon having rounded edges, a rubber tire chambered on the inner side and provided with lateral flange extensions, which rest on the outer face of the rim and against the rounded edges of the same, annular lash plates on the outer chambered part of the tire and the lateral flange extensions, bolts passing through the wheel and through the ash plates and provided with nuts for mak ing airtight joints between the rim edges and the tire, and means for supplying compressed air to the interior of the tire, substantially as set forth.

2. The combination of a wheel, a metallic rim thereon with rounded edges, a rubber tire with cellular chambers on the inner side and provided with lateral flange extensions, which rest on the outer face of the rim and against the rounded edges of the same, annular lash plates on the outer chambered part of the tire and the lateral flange extensions,

bolts passing through the Wheel and through name to this specification in the presence of the lash lates and prowded with nuts for two subscribing Witnesses.

making airtight joints between the rim edges and the tire and means for supplying com- GUTHBERT BURNETT 5 pressed air to the interior of the tire, sub- Witnesses:

stantially as set forth. I ARTHUR CowEN ALDER,

In testimony whereof I have signed my H. NIXON.
